The CS5266 is a high-performance Type-C/DP1.4 to HDMI2.0b converter, designed to connect a USB Type-C source or a DP1.4 source to an HDMI2.0b sink. The CS5266 integrates a DP1.4 compliant receiver, an HDMI2.0b compliant transmitter. Also, two CC controllers are included for CC communication to implement DP Alt Mode and power delivery function, one for upstream Type-C port and another for downstream port. The DP interface comprises 2 main lanes, AUX channel, and HPD signal. The receiver supports maximum 5.4Gbps (HBR2) data rate per lane. The DP receiver incorporates HDCP1.4 content protection scheme with embedded key for secure transmission of digital audio-video content. The HDMI interface includes 4 TMDS clock/data pairs, DDC, and HPD signal. The HDMI transmitter is capable of supporting up to 3Gpbs data rate, quite adequate for handling video resolutions up to FHD 1080p 120Hz andUHD 4k 30Hz formats. The HDMI transmitter incorporates HDCP engines which support HDCP1.4. With the inclusion of HDCP, the CS5266 allows secure transmission of protected content. Embedded key is available that provides the highest level of HDCP key security.The CS5266 is a highly integrated single chip suitable for multiple market segments and display applications, such as the dongle, docking station etc
